"In software development, Git /ɡɪt/ is a distributed revision control and source code management (SCM) system with an emphasis on speed. Git was initially designed and developed by Linus Torvalds for Linux kernel development in 2005. Every Git working directory is a full-fledged repository with complete history and full version tracking capabilities, not dependent on network access or a central server." - Wikipedia

At first it's a little difficult to get used to it, but the day you really need to know what you were wearing at your third cousin's best friend's brother's 17th birthday party, those photos will come in handy.)
